^{Product Features}

 

 

High surface area: LSG films have a large number of three-dimensional micro nano porous structures, providing more active sites and diffusion pathways.

High thermal stability: LSG can maintain stable structure and performance at high temperatures.

High conductivity: LSG theoretically has good conductivity and can be used for the preparation of electronic devices and sensors.

Flexibility: By adjusting laser parameters and preparation environment, the surface morphology and properties of LSG can be flexibly controlled.

Application Fields

 

Stress Sensor: LSG has excellent mechanical strength and conductivity, capable of responding to various forms of external stress and converting them into electrical signals for detection.

Biosensors: LSG has excellent electrocatalytic activity and strong adsorption capacity, and can sensitively detect biomolecules such as glucose, dopamine, hydrogen peroxide, nucleic acid, and insulin.

Gas sensor: The three-dimensional micro nano porous structure in LSG provides more active sites and diffusion paths for gas detection, which can be used for the detection of gases such as ammonia and hydrogen.

Temperature sensor: The resistance of LSG has a negative exponential relationship with temperature, so it can be used as a temperature sensor to monitor changes in body temperature and battery temperature in real time.

Humidity sensor: The combination of LSG and graphene oxide has high sensitivity to humidity changes and can be used for humidity detection.
